How to get vector of options from server.R to ui.R for selectInput in Shiny R App -


> > <> > <> <> , "विकल्प चुनें:", शिविर)

जहां शिविर विकल्प के वेक्टर होने चाहिए। यह वेक्टर एसक्यूएल क्वेरी पर निर्भर करता है जो सर्वर स्क्रिप्ट पर चलता है और कैंप की आईडी लौटाता है:

server.R 

  df1 & lt; - getCamps ("तारीख" ) शिविर & lt; - अद्वितीय (df1 $ idCamps)   
 जब मैं ऐप चलाता हूं ui.R नहीं जानता कि "कैंप" क्या है क्योंकि यह केवल सर्वर में बनाया गया है। r फ़ाइल । मैं सर्वर में बनाए गए शिविरों के वेक्टर को कैसे पार करूं? Ui.R फ़ाइल में फाइल कर सकते हैं ताकि वे अब selectInput चयनकर्ता में से चुनने के विकल्प हो?   
 
 
 आपको सर्वर में इनपुट ऑब्जेक्ट बनाने की आवश्यकता है। आर, और  आउटपुट  सूची के भाग के रूप में इसे यूरी पर वापस लौटें:  
 सर्वर में। आर:  
  df1 & lt; - getCamps ("तारीख") शिविर & lt; - अद्वितीय (df1 $ idCamps) आउटपुट $ शिविर चयनकर्ता & lt; - renderUI ({selectInput ("चर 1", "विकल्प चुनें:", as.list (शिविर))})   
 में ui.R:  
  uiOutput ("campSelector ")
